PAGE PAGE 8 PAGE 10万吨/年合成氨脱硫系统填料塔的初步设计 指导教师：邓 梅 2010级化工专业 学号 201013657姓名 廖宇 摘要 填料塔是塔设备的一种。塔内填充适当高度的填料，以增加两种流体间的接触表面。例如应用于气体吸收时，液体由塔的上部通过分布器进入，沿填料表面下降。气体则由塔的下部通过填料孔隙逆流而上，与液体密切接触而相互作用。结构较简单，检修较方便。广泛应用于气体吸收、蒸馏、萃取等操作。经过步的计算得出这次设计的填料塔直径4m，高5.4m。 关键词：填料塔、设计、脱硫。 100000 tons / year synthetic ammonia desulfurization packed tower design Instructs teacher: Deng Mei 2010levelofchemicalindustryspecializedstudent number 201013657 name liaoyu Abstract The tower is a tower equipment. The tower is filled properly high filler, with a two increase in fluid contact between the surface. For example used in gas absorption liquid from the upper part of the tower, through distributor into decline, along the surface of packing. Gas from the lower portion of the tower filler pore through the upstream, and the liquid in close contact and interaction. The structure is simple, maintenance is convenient. Widely used in gas absorption, distillation, extraction and other operations. After further calculated the design of the tower diameter 4m, high 5.4m.
